PAPER-BOX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 602,140, dated April 12, 1898.

Application filed April 19, 1897. Serial No. 632,791- (No model.)

To all whom it mag concern.-

Be it known that we, .CHARLES HENRY PALMER and JOHN WILLIAM DENMEAD, citizens of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Im movements in Paper-Box-Making Machines; and we do hereby declare the following to be a description of the invention, such' as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings.

Our invention relates to that class of'paperbox-making machinery in which a box or sheath open at one or both ends-is made from a continuously-fed strip or ribbon of paper.

In our invention the box is formed bya series of vertically-rotating arms provided with laterally-projecting intermittently rotating and vibrating dies or formers journaled therein. These dies press from the continuous strip of paper a piece that is severed in cooperation with the die-pressure thereon,which piece is partially formed as it is forced by the die through an aperture in the table into a fixed oscillatingv die former or folder. This die vibrates on itspivot to fold one inner edge of the box over the die journaled in the rotating arm, which die then revolves against a spring securedbeneath the aperture in the table to fold over the other part that is glued of the same edge of the box. The die, with the folded box thereon, then presses against a series of rollers secured to a curved springpressure arm that is elastically held in position concentric with the onward movement of the die. means of its crank, friction-roller, and cam track, the paper having had the glue placed thereon at intervals to secure the adhesion of the parts so folded. As the arms are rotated successively the completed box or sheath is pushed off therefrom by a sliding dischargering encircling the die and actuated by a camtrack,and the arms continue in their rotation, carrying the strip of paper to be folded over the dies again down through the aperture in the table, that is made with rigid walls to aid in the successive formation of boxes. The paper is perforated at proper intervals The die is caused to revolve by.

cular aperture F in the lower presser-roller,

over which the paper passes between the flanges of two rolls that hold it firmly in place as it ispresented to the knife that severs therefrom the portion from which the box is made, ashereinafter described. The glue is applied by means of a fluted roller revolving in a tank of hot glue and provided with intermittent raised surfaces that are alternately brought in contact with the paper at regular intervals to apply the glue at the proper place. An adjustable guide-roll receives the paper from the glue-roll, over which it passes as it enters the machine. This adj ustable guide-roll is caused-to increase or decrease the distance of travel of the material after the glue has been applied to assist its partial drying or hardening to render its adhesive quality certain.

In the drawings,'Figure 1 represents a plan view of our machine. Fig. 2 is a side elevation taken from the right-hand side of the machine. Fig. 3 is a side elevation on the opposite side, partly in section. Fig. 4 is a side View of the oscillatingdie orformer; Fig. 5, a sectional view of the same. Fig. 5 is a detail sectional view of the table withits aperture and the pressure and folding devices. Fig. 6 shows the knife-lever and its actuating star-Wheel. Fig. 7 shows the feed-rolls in elevation. Fig. 7 is a sectional view of feedrolls. Fig. 8 is a detail view of their intermittent actuating mechanism. Fig. 9 is a view in perspective showing a section of the rotating arm and the die journaled therein, the vibrating crank secured on the'end of the same, its adjustable stop secured on the rotating arm, and the spring-rod and frictionroller, that imparts the vibrating action to the die. Fig. 10 is a sectional view of the same, also showing the box-discharging ring and its actuating arm and pin that pushes the box from the die when completed; Fig. 11, an end view of the same; Fig. 12, a plan view of the fluted gluingroll and its scraping springcleaner. Fig. 13 is an end view of the gluing-roll; Fig. 14, a plan view of a piece of the paper strip or material from which the box is formed, showing the figured surface and the controlling-aperture that regulates its feeding into the box-making machine.

In the drawings a main driving-shaft R, actuated by a belt-pulley R, causes a gearwheel R to revolve and impart motion to the pinion R on a parallel shaft R having keyed thereon a cam-wheel 0 that carries a crankpin that actuates a pitman Bfl the other end of which is secured by a crank-pin to a pawlbearing plate B, which is loosely journaled on its shaft 1) and provided with a pawl B by the side of the ratcheted plate B, that is keyed thereon and imparts an intermittent movement to the gear-wheel. The pawl and ratchet may be disconnected by raising the pawl and the gear of the feed-rollers rotated forward or back to secure their adj ustment in connection with the feed-tooth F of the feed-roll and the perforated figured boxmaking strip F. This gear-wheel b imparts an intermittent motion to the feed-roll pinion b that actuates the gear-wheels ff of the feed-rollers and causes the paper or material F, from which the box is to be formed, to be fed forward. The upper feed-roll carries flanges F that press upon the paper strip, and the feed-flanges F upon the lower feed-roll serve as guides for the edges of the paper strip, and at one part the upper flange F is cut away, as at F, to free the pressure of the flanges of the roller as it revolves, affording a free movement forward of the strip by the feed-regulating tooth F, that enters the aperture F in the paper. This regulation is important to regulate and control the pa per to be cut in proper relation to the position of its figured surface. The knife H is attached to the plate N, that is secured to the knife-arm E, which is pivoted at its rear end at 6 above the horizontal plane of the table and provided with a knife near the center of the pivoted arm, which arm is extended to a point below the table and is actuated by the star-wheel E upon the main shaft to press down upon the knife-arm below the plane of the table, and thus secure a rightangle out upon the strip of paper from which the box is to be formed. The pivoted rotating die A journaled in the arm A, presses the box-blank down through the aperture in the table, the fixed walls of the aperture forming the lower edge and two sides, (see Fig. 5,) and thus the partially-formed box is brought in contact with the lower jaw of the fixed oscillating die or former M and its spring pressure plate m, secured therein. This oscillating die or former M is pivoted at M beneath the aperture in the table and held to its normal position by means of its crank-arm n, secured to its pivot-journal and its spring 0. The edge of the die A over which the first fold is made, has its plane slightly below the edge on the opposite side. This die or former M will be oscillated and close the inner edge of the box over the upper edge of the rotating vibrating die A The arm K is secured to the side of the aperture in the table and provided with spring pressure plates against which one side of the die presses to fold that side of the box, as shown in Fig. 5.

Arm 1? is pivoted at one side of arm K beneath the table and is provided with frictionrollers and a springpressure rod P and thumb-set-screw nut 13 to regulate its pressure under the stress of the dies A of the rotating arms that are caused to revolve by means of their crank-arms A and frictionroller a being brought in contact with the cam-track D. A spring-rod a pivoted at a to said crank-arm, will pull the same to its -normal position as it continues its forward travel by the rotation of arm A and passes over cam-track D.

The oscillating former M has a crank-arm n, to which is secured a holding spring-rod O, that causes it to return to its normal position after it is released from the pressure of the rotating die A The spring-rod a pivoted to the crankarm at a will cause the die A to return to its normal position, and when the arm is rotatin g to its upper point the discharging-arm A with ring A is actuated by its pin A, which is brought in contact with the cam-track A and caused to push the box from the die, when the cam-track A whichtracks are secured to the arched bar A will force the discharging-arm back, so that its ring will be within the groove a and the die left free to form another box as it is continued in its rotation.

The device for placing the glue upon the material as it enters the machine consists of a revolving glue-roller S provided with alternate fluted flat surfaces S and a scraper C. This glue-roller is journalcd on a shaft S, that is provided at its outer end with a ratchet-wheel S, secured thereon, and a loosely-supported pawl and crank-arm S provided with a pawl that is moved by the rod r, that is actuated by the crank r, secured on the side of the pinion R This mechanism admits the adjustment of the pawl and ratchet to regulate the position of the roller in its relation to its actuating rod and imparts to the gluing-roller an intermittent rotary movement to place the glue as it is hot at regular intervals upon the corrugated surfaces of the gluing-roller, that has a vertical movement imparted to it to apply the glue to the material of which 'the box is to be formed.

The glue-roller shaft is journaled upon the arms 0 that are secured within a vertically- Vibrating frame 0 that is pivoted on each side of the machine at C G. This frame has an intermittent vertical movement imparted to it by means of a vertical rod 0 that is secured to the arm 0 that is secured to its supporting actuating-arm 0 that slides in its guiding-standard c, secured to the table. This arm is actuated by means of a pivoted lever 0, provided with a slotted end 0 and a securing-pin 0 This lever vibrates upon its axle O, as its other end is caused to rise by the cam-wheel C, revolving against a friction-roller against the strain of a returning spring-rod C The vibration of this pivoted lever G imparts an intermittent vertical movement to the rod 0', that hooks beneath the vibrating frame 0 and imparts an intermittent vertical movement to the glue-roller, causing it to be raised and brought in contact with the strip of box material and apply the glue at the desired point.

The guiding-roll T, secured to its adjustable frame, slides upon its supporting-bars T, and by means of its adjusting-screw T? in the outer bar T the guiding roll may be moved to or from the gluing-roll to any dis tance required topermit the hardening or setting of the glueon the material as it passes to the machine.

t is the'steam-pipe for keeping the glue in the reservoir S in proper condition by heat conveyed to its steam-chamber beneath the glue.

In the continuous operation of the machine the printed and perforated strip (shown in Fig. 14) is fed forward into the machine, passing overthe gluing-roller to receive theglue on its under side and over the guiding-roll,

which reverses its direction and brings the glue on the upper side. The strip then passes under the spring-pressure fingers h to the feed-rolls between the strip-guiding flanges F so that the intermittently-feed-regulating I tooth F enters the aperture F in the macured beneath the aperture in, the table, and

folds the box-blank over three sides of the die. The die moves into contact with the lower projecting jaw of the oscillating folding-die M and its spring-pressure plate m, and the continued forward movement of the rotating arm and its die will cause the oscillating die to vibrate on its pivot, and its upper jaw will fold one projecting side flap of the box over the die j ournaled in the rotating arm as it revolves. As it continues its movement over the series of rollers on the springand described.

pressed arm the box is caused to assume an inverted position as its; die is reversed by means of its crank-arm A that comes in contact with the cam-track D, securedto the frame, and'thus the other projecting side flap of the boxis folded over, and the'glue which has been applied on this side causes the adhesion of the parts thus folded. As the crankarm passes off of the track the spring-rod a pivoted to the crank a and secured beneath the second following arm, will pull onhthe crank, causing it to revolve and restore the The adjustable shown in the drawings, and as the rotating arm mov es on the box-discharging device is retracted to its normal position by means of the cam-track A and the arm continues to revolve in itssuccessive operation.

The material or strip of paper from which the boxes are formed may be of any proper kind applicable therefor, whether it is perforated or not or whether there are one or more perforations, so far as the operation of. the box-forming dies is concerned; but our invention is more particularly designed to It is well known, that a very slight variation in the feed or movingforward of the strip is liable to cause considerable displacement of the figured surface thereon in a series of operations, and we find it necessary to main tain the proper place of each individual printed or figured piece of paper from which the box is formed in order to secure the uniform locality of the colors or designs upon the completedbox.

The adjustment of the device that applies the glue is important to enable the placement of the glue at the proper relative point in connection with the printing andfolding devices.

In our machine we contemplate the use of interchangeable dies for making different sizes and shapes of boxes.
